Flat Reeling Cable with Steel Wire – PUR Reinforced Drum Cable
Designed for heavy-duty power and control supply to cable reels, motorized drums, and festoon systems, this flat reeling cable with steel wire combines a flexible core with a high-strength galvanized steel carrier and a tough PUR outer jacket. It is engineered to withstand the combined tensile and torsional stresses found in dynamic reeling applications, making it a reliable choice for port cranes, material handling, and automated machinery operating in harsh industrial and outdoor environments.
Key Features and Benefits
- Superior Flexibility with High Tensile Strength: Finely stranded oxygen-free bare copper conductors ensure excellent conductivity, while the integrated steel wire reinforcement (optional) handles high tensile loads without restricting the cable’s natural flexibility.
- Exceptional Abrasion, Flex and Torsion Resistance: A special structural design, optimized cabling lay length, fine copper stranding, and a nitrile rubber compound prevent core breakage under constant bending, twisting, and reeling cycles.
- Effective EMI Protection (Optional): Available with a tinned copper wire braid shield that effectively suppresses external electromagnetic interference, ensuring signal integrity for control and data transmission in industrial networks.
- Extended Service Life and Operational Safety: High-strength galvanized aircraft-grade steel wire cores, jute rope fillings, and a non-woven fabric buffer wrap absorb mechanical stress, significantly increasing cable longevity and safety in vertical reeling and long-travel applications.
- Weather, Oil and Tear Resistance: A proprietary weather-resistant nitrile elastomer or premium imported polyurethane (PUR) jacket provides outstanding resistance to mineral oils, UV radiation, ozone, and mechanical tear, making the cable suitable for both dry indoor and wet outdoor installations.
Typical Applications
This PUR flat reeling cable with steel wire core is specifically built for cable reel and drum systems that demand high mechanical endurance under combined tensile and torsional loads:

4. FAQ
Frequently Asked Questions – Flat Reeling Cable with Steel Wire
Is the steel wire core mandatory, or can I order the cable without it?
The galvanized steel wire reinforcement is fully optional. If your application does not involve heavy tensile loads, the cable can be manufactured with only jute rope fillings to maintain roundness and flexibility. For long vertical reeling distances or high-speed reeling, we recommend including the steel wire core.
Can I add a braided shield for electromagnetic interference (EMI) protection?
Yes. An optional tinned copper wire braid shield is available. It provides effective protection against external EMI in control and signal cables, and is specified as an addition to the standard construction.
Which jacket material is more suitable for permanent outdoor installation?
For continuous outdoor exposure to UV, rain, and wide temperature swings, we recommend the imported PUR (polyurethane) jacket. It offers superior resistance to UV radiation, ozone, and abrasive contact compared to the nitrile elastomer compound, which is also weather-resistant but better suited to intermittent outdoor or demanding indoor environments.
Is this flat reeling cable compatible with motor-driven drum systems?
Absolutely. This cable is purpose-built for motorized cable reels, spring-driven drums, and powered hoisting systems. Its special structural design handles the simultaneous tensile and torsional forces typical of powered reeling operations.
What voltage rating can this cable support?
The standard design is rated for low-voltage power and control circuits up to 0.6/1kV. If your installation requires a different voltage class, we can adjust the insulation thickness accordingly. Please speak with our engineering team about your project’s electrical requirements.
Can I request a sample or a custom reel length?
Yes. We provide sample sections for evaluation and can supply continuous lengths cut to match your drum dimensions. Contact our sales engineers today to discuss your specifications or request a formal quotation.
